A stufling boX G? is providedto prevent leak age outof the tank alongthe shaft G. It

will be understood, oflcourse, that the gate F when in its lower open position should.

not interfere with the free discharge through th corresponding weinnotch, and for, the

samereason theguidesE and spur gears G should be so located as notto interfere with the discharge through the weir notch.

i In the apparatus shown in Figs. 1 to'6,

we. have provided means for automatically shifting the gate Flinto its closed position and back into its open position in response to variations in the height ofliquid level on the supply side of the weir. This we accomplish by meansof an electric motor H, and controlling means for this motor-automatically. adjusted by the rise, and fall in the liquid level in the chamber A, as by means ofthe float employedto operate the record-v ing'fmechamsm. 'As shown in the drawings,

connected .to the conductors 1 andB, so that the electromagnet is energized whenever and while the contacts Tand T are'connected by the member Q; that is, while the gate F is in its closed position. The weighted armature P of the electromagnet P carries a O at its free end. Vhen the electromagnet P is energizedland thearmature P attracted, the marking device 0 1s pressed against the record chart, tracing a line Z, which is interrupted whenever the member Q, is shifted to disconnect the contacts T and T,

the weight of the armature P then carrying the marking device 0 out of contact with the record chart.

In the modified construction shown in Fig. 7 the gate FA is horizontally movable, working in guides e, c and 6 which are formed with wedging surfaces 6 and e corresponding to the'surfaces E and E and cooperating with inclined surfaces on the gate FA, similar to the surfaces F and'F on the gate F. In the particular construction shown in Fig. 7 the gate FA is provided with an operating stem F which projects through the stufling box A secured to the side wall of the tank A. Externally of the tank A the stem F is connected to an operating lever V, by means of which the gate FA may be manually shifted back and forth between its open and closed positions at the will of the attendant. The gate FA is formed with a notch F which registers with the corresponding notch C in the open'position of the gate. In this form of our invention the position of the lever V indicates whether the gate FA is open or closed. A record of the position of the gate FA at different times is obtained by means of a marking device 0A, which is pivotally mounted at 0 and is provided with a weight 0 tending to hold the marking point away from the record chart carried by the drum L. The weighted lever U, pivotally mounted on the weir plate support or partition CA, is provided with an arm U which is engaged by the lug F on the gate FA as the latter is moved into its fully closed position. This shifts the lever U out of its normal position in which it rests upon the stop C. When the lever Uisth'us shifted it elevates the rodU passing upward through the top wall of the tank A into the bottom of the case K, and thereby causes the marking device ()A to beithrown against the record surface, while in the normal positionof the lever {Lain whichthe weighted arm engages the stop O, the marking device 0A is held out of contact with-the chartby thelweight. 0
